Tire tread



FIG. 1 is a perspective view if a tire tread showing my new design, it being understood that the tread pattern is repeated throughout the circumference of the tire tread, the opposite side being the same as that illustrated; and

FIG. 2 is an enlarged fragmentary plan view of the tire tread thereof further showing my new design.

The broken line disclosure of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown along the right tread shoulder in FIG. 1 . 

The ornamental design for a tire tread, as shown and described.
